Proof step 70 from proof refine-remap (previous step)

m < # avols0[default-volid], ebm-cons(avols0), ebm-vol-inv(abs(avols0[default-volid])), default-volid ∈ avols0, ⌊err1⌋ ⊦ abs(avols0[default-volid]) = abs(avols0[default-volid][m, unmapped]), unmapped = abs(avols0[default-volid][m, unmapped])[m]

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: ebm-vol-abs name: abs-at seq: ⊦ n < # evol → abs(evol)[n] = abs(evol[n]) subst: [n, evol] → [m, avols0[default-volid][m, unmapped]] flags: <all paths>

Additional information

Used simplifier rules: ⊦ m < # evol → evol[m, leb][m] = leb; (s)% ⊦ abs(unmapped) = unmapped; (s)% ⊦ # evol[n, leb] = # evol; (s)% ⊦ m < n ↔ ¬ n ≤ m; (ss)% ⊦ m < n → (n ≤ m ↔ false); (s) Used terms: m, avols0[default-volid][m, unmapped]
